Karazin popup.description2 Object of the research is the physical process of the formation of electromagnetic fields in systems with a periodic sequence of complex composition layers with complex response to electromagnetic excitation, which are inherent gyrotropic, anisotropic, biisotropic and chiral properties and in the waveguide with bulk perfectly conducting inclusions. The work aim is to develop efficient electrodynamic model and numerical-analytical algorithm for analysis of characteristics of the scattering electromagnetic fields and the eigen oscillations of the control devices of electromagnetic field of microwave and optical range which are based on the resonant scatterers of complex composition and their sequence. In this work a mathematical model magnetophotonic crystals based on the sequence of ferromagnetic layers, which takes into account dissipative losses, and macroscopic metamaterial made in the form of an anisotropic composite medium consisting of alternating four-layered inhomogeneities has been developed. A mathematical model based on the analysis of both eigenmodes of layered infinite media and the scatterers fields of finite periodic sequences. The conditions for amplification of both the Faraday effect and circular dichroism in magnetophotonic crystals was revealed out. A generalization of the method of contour conjugation for the case of full-wave analysis of three-dimensional waveguide inhomogeneities in the form of a perfectly conducting cylindrical inclusion with a gap, which is placed in a rectangular waveguide, has been done. An efficient numerical algorithm to calculate the scattered fields of thin 2D-periodic optical structures and their sequence has been developed. The algorithm uses the mapped pseudospectral time-domain method and the frequency domain method of the transfer matrices. It is effective for analysis of the electrodynamic properties of arrays with arbitrary composition period. Discovered physical effects and developed numerical - analytical algorithms are the basis for the designing of multifunctional devices of passive and active control of electromagnetic fields with unique characteristics. The obtained results demonstrate the topicality of further research of comple composition scatterers and their periodic sequence. Proposed algorithms can significantly extend the class of the investigated structures by including in it of a periodic planar array of scatterers of complex shape, and the same active or nonlinear media. The obtained results are focused on improving characteristics and extending the functionality of microwave and optical devices. The data that obtained during research can be used to design artificial media with the specified parameters and filters, selective and high-impedance surfaces, antenna radomes, components of optoelectronic communications, laser mirrors etc. DIFFRACTION, ELECTROMAGNETIC WAVES, WAVEGUIDES, GRATTINGS, FINITE PERIODIC SEQUENCE, METAMATERIALS Product Description popup.authors Антюфєєва М.
